This is what I get when entering the prescribed code in Terminal (Mac):
~ % cd /Users/marwan/Downloads
cd TheProfessional.app/Contents/MacOS
chmod +x TheProfessional.app/Contents/MacOS/The\ Professional
chmod: TheProfessional.app/Contents/MacOS/The Professional: No such file or directory
I'm using Apple Silicon M1 with MacOS Ventura.
